Flow Coefficients (ID=112)

The flow coefficient C_v is a valve sizing designation commonly determined by laboratory test. It corresponds to the flow rate of water through a valve in US gallons per minute at 60�F with a differential pressure drop of one psi.

With the C_v coefficient known, the following values can be calculated:
